Is it hard removing a transmission? - PeachParts Mercedes-Benz Forum

Due to my recent issues with my transmission ('85 300TD) I'm looking at getting a similar trans from the same year.

How hard is it to remove a trans in a pull-a-part environment?

What tools are required?

How much does a 722.315 weigh?

Thanks

Depends on the upullit. Many have the cars up on welded wheel supports. Mine does, but does not allow the use of jacks ( which makes "dropping" a trans problematic). They weigh about 100-110 lbs. Need 17mm wrenches, sockets, extensions, 10mm allen head for starter bolts.

Having done this job recently on a w123 and w201, I'd think really hard about pulling one in a yard. It is not a technically demanding job but it is very labor intensive....having evey tool required for the job in a tool bag would be a tedious shopping list as I used numerous implements for propping, prying, etc. If the yard will let you pull the engine/tranny as a unit, then you can easily unbolt the transmission and leave the engine for them to stick up on a parts shelf somewhere. That would make the operation many magnitudes easier in my opinion. How is the doner vehicle stored? If on a low rack, you may have an easier time of it. If not, and they will not let you put the car solidly up on TALL jackstands, I'd pass on the deal. The trans itself can be handled by one man once free of the engine but if trying to cherry pick it from overhead you'd be at risk of any number of painful consequences.

Talk to the folks at the yard and see what is allowed. The rules could make things easier for you or they could make it nearly impossible.

go with a buddy and pull the engine and trans together remove trans when they are both out on the ground much easier. Metric sockets and wrenches, regular stuff, I've done it 2wice and I ain't no mechanic. Find a manual from a 240 and put that thing In there, not too hard.

Our Pick N Pull have the cars up on welded rims for stands. they do not allow jacks to be used.
They do have a bunch of A frames/chain hoists on wheels that can be used free of charge to pull engines.

Last April I pulled an engine with the trans in 3 1/2 hours by my self. then
separated the two on the ground, and left the trans.

If you try to just remove the trans w/o a jack or something to let down
safely, plan on the possibility of getting hurt. the automatic trans have
to be 100 lbs. or so.

removing a 4 spd manual is no problem, they don`t weigh much. I have pulled two by my self.

If your able to find a transmission floor jack you would be better off by far.I'm sure they can be rented.Other wise your looking at 100 to maybe 125lbs of dead weight just above your arms.You better be ready and have helping hands!
Good luck

If your upullit doesn't allow jacks you will have to get creative. I have used seat cushions. I have also heard of the idea of using 3 cardboard boxes nested together. Drop the tranny on the three together, then cut the outer one away, then the second. The tranny will probably crush the third.

If you go for one, bring a hacksaw (to cut exhaust, motor mounts, whatever), penetrating oil, rags.

Thanks guys!

This all sounds very creative...
